ELECTRONICS Troubleshooting Tips By Jim Sparks The term avionics is often associated with flight deck displays, navigation systems, auto flight systems, and communication devices. Such manuals usually include troubleshooting procedures. Place the ICs on the base, and give the input to the controller, and then check whether the output control signals are coming or not at appropriate pins. It is very common for the hobbyists and circuit designing learners to anticipate the desired or actual results after completion of the circuit at once. The unexpected behavior exhibited by the circuit is due to improper locating or soldering of components, component damage due to aging, faults, overheat, and so on. Variable Power supply with a metered indication. If the equipment you’re troubleshooting employs dangerous voltages, do not work alone. It is an essential part of troubleshooting. Repairing may also include replacement of a component. For minor problems, troubleshooting requires a little knowledge about the circuit and its components’ working because it involves checking the connections only. Or, if this resistance were open or shorted, what effect would it have on the operation of the circuit I’m working on? Replace a suspicious unit with a known good one-this is one of the best, most commonly used troubleshooting techniques. What are Ferromagnetic Materials – Types & Their Applications. To be an effective troubleshooter, the technician must also be able to quickly isolate faulty components and repair the defective circuit. Hope this information certainly gives a chronological way of troubleshooting technique and further any help regarding this concept you can reach us by commenting in the comment section provided at the end of this article. 6. Look for the loose, bad connections and also check the ground paths. This value should be within 10% of the rated value. None of the computers are able to communicate with each other. Note: If anyone of the above-mentioned conditions requires an immediate repair, then go for the required action like de-soldering the shorted points, soldering the loose parts or the connections, replacing the burnt components with the new ones, etc. They provide convenient connections to the circuitry for adjustment and/or testing. They follow certain logical steps when looking for a defect in a piece of equipment. Examine the output module. Some of the most difficult troubleshooting issues relate to symptoms which occur intermittently. However, the major problems of these circuits require a deeper knowledge of the circuit operation and the way of using various troubleshooting tools. Check the voltage across the individual components, and if any component doesn’t show any voltage across it, then switch off the supply, and then again test the components by respective meters like LCR for the capacitor, diode by multimeter, and so on. You should be relatively set to begin Electronics troubleshooting! Here are a few tips that will help you to troubleshoot your circuit. Reviewed in the United States on July 17, 2014. To troubleshoot, you simply follow logical, step-by-step procedures to arrive at a solution. Instead of immediately diving in and haphazardly attempting anything to get the equipment running, first step back and determine how is … REPAIRING Recognizing the way, a circuit may malfunction is a key … To be an effective troubleshooter, the technician must also be able to quickly isolate faulty components and repair the defective circuit. If this device or process has been historically known to fail in a certain particular way, and the conditions leading to this common failure have not changed, check for this “way” first. Apply appropriate troubleshooting techniques to electronic circuits or systems and perform test procedures. Let’s look at some major types of failures that you will encounter as an electronics technician. Visual inspection also aims to identify lousy solder joints. Troubleshooting process involves checking the terminal voltage across different components and devices in the circuit; checking the continuity of the current for open circuit faults, components like resistor, capacitor, transistors, and their status checking whether they are functioning or not, and so on. These terminal blocks provide convenient connection points to join wires together, In electronics this often is the result of components that are thermally sensitive (since resistance of a circuit varies with the temperature of the conductors in it). For this reason, we shall first review meters before we discuss other test equipment and troubleshooting techniques. Don’t forget that other people may be coming along after you, and they need to understand the problems … Check for the exploded or burnt parts of the circuit by seeing and smelling them. 9. If the problem still isn't fixed, you can try other troubleshooting techniques. Greetings once again, Troubleshooters, and welcome to Troubleshooting Thursdays! The last two times this happen… May 16, 2019 - Explore Walter's board "Electrical Troubleshooting" on Pinterest. Example 1: A “star” topology communications network between several computers has failed. Test the main controller base power supply with respect to the ground without placing a controller on it. • to get the whole story you must check voltage across the float, this is especially true when it comes to mechanical floats. - Structure & Tuning Methods.
